This invention appertains to new and useful improvements in seaming devices. of the lead burning type.

The principal object of the present invention is to provide a seaming device of the lead burning type wherein a sup-port isafforded for the form iron, which will eliminate tedious exertion on the part of the operator and which will allow the form iron to be used by unskilled workmen.

Another important object of the invention is to provide a device of the character stated wherein the various parts can be readily adjusted to meet the various demands for such a device.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a front elevational view of the apparatus.

Figure 2 is a side elevational View.

Figure 3 is a cross sectional view taken substantially on the line 3-3 of Figure 1.

Figure 4 is a fragmentary detailed sectional view taken substantially on the line 4-4 of Figure 1.

Figure 5 is` a sectional View taken substantially on the line 5-5 of Figure 3.

Figure 6 is a sectional view.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes an elongated I-beam along the top flange of which is ridable the grooved block 6 laterally of which extend the flanged arms '|-'I. These arms 'I-l are provided with vertical bores at their ends for receiving the upstanding posts 8 8 each of which is provided with a pivotal suction cup- 9 at its lower end. Set screws I are provided at the outer ends of the arms 'I and these are feedable inwardly to engage the posts 8 to retain the posts in proper adjusted positions with respect to the arms l.

It will be observed that such retention means as this is provided at each end of the beam 5. In other words, there are two blocks 6 and two sets of arms '1 1 as well as posts 8--8 and cups 9 9. With this means the beam is supported in proper position with respect to the joint to be seamed.

A U-shaped carriage II receives the lower flange of the I-beam and short shafts I2-I2 are journaled through the upright flanges thereof. Each of these shafts I 2 is provided with a gear I3 at its inner end and a hand wheel I4 at its outer end. Each lower flange of the I- beam 5 is provided with longitudinally extending rack teeth I5 with which the corresponding gear I3 meshes.

Depending from the bottom of the U-shaped carriage Il is the barrel I6 receiving the vertically adjustable shank Il of the form iron I8 which is pivotally secured to the member Il as at I9. A coiled compressible spring 2i! is located in the barrel I6 and exerts tension downwardly on the member Il and the form iron I8. The barrel It is provided with openings through which the retaining pin 23 is disposed, this pin being disposed through a slot 2l in the member Il as is clearly shown in Figure 3. The pin 2B has a handle 22 at its outer end.

The arms 'I-l in the setting up of the device are adjusted apart on the beam 5 to the desired extent as suggested in Figure 1 and held in these positions by the set screws 23.

Of course, the apparatus is used in a vertical position as suggested in Figure 1 and in seaming kettles and other receptacles the form iron I8 is lowered to the bottom of the receptacle. As is well known, the lead sticks or strips are placed in the form and melted by a blow torch. The form iron is fed upwardly by rotating the hand Wheels I4 and the seam is made continuous by continuous dropping of the lead strip and application of the heat by a blow torch or the like.

While the foregoing specication sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:-

l. A seaming apparatus of the character described comprising an elongated guide member, a carriage carried by the guide member, a form iron carried by the carriage, feed means between the carriage and the elongated guide member, and removable supporting means for the said elongated guide member, said supporting means consisting of a pair of adjustable blocks on the elongated guide member, arms extending laterally from the blocks, posts extending through the ends of the arms, detent means at the ends of the arms for engagement with the posts, and suction cups at the work engaging ends of the posts.

2. A seaming apparatus of the character described comprising an elongated guide member, a carriage carried by the guide member, a form iron carried by the carriage, feed means between the carriage and the elongated guide member, and supporting means for the elongated guide member, said supporting means consisting of a plurality of posts each provided with a suction cup at one end for engagement with the work for holding the guide member to the work, and adjusting means between the guide member and each of the posts.
